The buffering range covers the weak acid pK a 1 pH unit. We can easily tell the functional group -COO from this formula, but it is harder with C2H3O2. Answer : NH4C2H3o2 is base What is an acid, base, neutral ? 1. Finding the pH of a weak base solution is very similar to that for a weak acid. It is probably a bit alkaline in solution. An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance. NH3 is a weak base (Kb = 1.8\times10-5) and so the salt NH4Cl acts as a weak acid. Is the resulting solution basic, acidic, or neutral? You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Direct link to rahulram05's post Is there any chart which , Posted 3 years ago.

A Lewis acid is any species that _____ an electron pair, whereas a Lewis base is a species that _____ an electron pair. Now if you have tried it, let's see. A short quiz will follow. Although the pH values of many familiar solutions fall between 0 and 14, in reality pH values can fall outside this range. So what I mean is that when a strong acid and a strong base react, the salt that gets formed is neutral because they both have equally neutralized each other's effect.
